Keelung Harbor Integrated Administration Building

The Keelung Harbor Integrated Administration Building (基隆港合同廳舍, Kiirun-kō Gōdō Chōsha) was constructed during the Japanese colonial period to serve as a centralized administrative hub for Keelung Port, Taiwan's principal northern gateway. Construction began on October 11, 1930, and the building was completed on July 15, 1934 (Showa 9). The project was part of Japan's broader effort to modernize Taiwan's port infrastructure and improve the efficiency of colonial administration.

The building was designed by Ryoichi Suzuoki (鈴置良一), an engineer with the Taiwan Governor-General's Transportation Bureau. The main structure rises four stories above ground with one basement level, reaching a height of 25.15 meters, while the distinctive corner tower extends to 31.2 meters. A three-story annex stands at 13.64 meters. The reinforced concrete structure employs an earthquake-resistant cross-beam column system, reflecting lessons learned from the devastating 1923 Great Kanto Earthquake. The exterior features textured face brick with granite accents at the waist course, marble and ceramic tile at the entrance, and rounded corners that reduce balcony projections — all contributing to a nautical aesthetic that evokes the imagery of ocean-going vessels.

Upon completion, the building consolidated eleven previously scattered port agencies: Keelung Customs (基隆稅關), Taipei Prefecture Harbor Bureau (臺北州港務部), Transportation Bureau Keelung Harbor Construction Office (交通局基隆築港出張所), Transportation Bureau Keelung Maritime Affairs Office (交通局基隆海事出張所), Keelung Post Office Wharf Branch (基隆郵便局波止場出張所), Government-General Plant Inspection Station Keelung Branch (臺灣總督府植物檢查所基隆分所), Government-General Pineapple Canning Inspection Office (臺灣總督府鳳梨罐詰基隆檢查所), Government-General Rice Inspection Office Keelung Branch (臺灣總督府米穀檢查所基隆出張所), Government-General Fertilizer Inspection Office Keelung Branch (臺灣總督府肥料檢查所基隆分所), Monopoly Bureau Keelung Branch (專賣局基隆出張所), and Keelung Police Water Patrol Unit (基隆警察署水上派出所).

During World War II, the building continued to function as the administrative nerve center of Keelung Port, which was a critical logistics hub for Japan's southern military operations. The port and surrounding area were subjected to Allied bombing raids in 1944-1945, though the building survived largely intact. After Japan's surrender in 1945, the building was taken over by the Republic of China government and renamed the "Harbor Building" (海港大樓) in 1947.

Today the building houses the Taiwan International Ports Corporation Keelung Branch, Keelung Customs (now under the Customs Administration, Ministry of Finance), the Central Weather Administration Keelung Station, and immigration offices. It was designated a Keelung City Historic Building on January 20, 2003, and was ranked 80th in Taiwan's "100 Historic Architecture Scenes" survey. The building stands as one of the finest surviving examples of Japanese colonial-era port architecture in Taiwan.
